TO ALL WHOM MAY CONCERN:

Be it known that "I, NICHOLRS H'. Bonorswnoi Gi Cedar street, in the city, county, and State of New York,,-huve invented a nervfniid iinpro'ved Granulnto'r for-Tobacco,. &c.; and I do hereby'declur e thatthe following-is a full-,feleuignnd ex act description thereof, which ,will enable those skilledin the urt to inakeu'nd use the salnc,vreference being had to the accompnnyingdraw ing, forming part of this specification, in which-- Figure 1 represents a vertical -centra.l' section'of this invention.

Figure 2' is .a horizontal section of the same. 7

This invention rel otes to an 'ap im'utus for the munufucture of whet is known by the trade ias killik-ken'ih tobacco. For such tobucco,'the scraps and wasteifrom cigur nianufactories, and. other parts of' the tobacco leaves or plunts, a re 'genernlly employed; and, in prepar'ingfsuid tobacco, the scraps and waste ei'e'first worked through iisieye of a 'cei'tain fineness, whereby the tob acco isgrun-ulated3. nd afteiwardsthis grnnulat'ed tobacco is separated from the, dust by neuns of a huii' sieve. :Ihis operation is generally performed by hand. 'It is very-tedious; und furthermore, the dust; cheated by it is exceedingly troublesonie'to the workincn and every-;

bodyin the room or building. Ali'these disudvantugcs m'e obviuted h'y myinvention, whieh'coliqists in- 9 closed box, provided with a movable shaft, on 'which is'mount'erl a sieve with'shurp teeth, un-djwitha'yielding open head, furnished with projections, which extend between the teeth of thesievc'insuch a, manner tlint, vhenthe box iefilled with tobucco scrnps-, or \izistetobacco, and a i'c'vo'lvin'g motion is imparted to the shuft and sieve, the tobncco is granulated by the notion of' the teeth of the sieve, and the projections on the yielding head; and;

if nails, pie cc slof wood, or other 'irnpuii'ties, (which he usually mixed with tobaccoscrapsj get in between the projections of. the head and the teeth o-f-tho sieve, the headyieldgund injury to the teeth of'th'e sieve, or to other parts of thc' machine is pneyented. Atthe some time, by the closed box, the escape of dust into the ro o m is prevented, ,und the tiperatio'n of granulntingtobacco ciin be effected with little trouble zin'd e x pense IA represents d'boii, made of tin, or any other suitable material, in the form. of a, c y1in'der,"or iu hny other suitable fd mvo ,shupo. This boih is provided with a cover,'B, whichismude to fit tigh,t, or which maybe s olileredto the body-0f the hoir, undlproj'id'cdwith a feed opening, which, in thnt case, must-be furni'shedwit h aitightly-fitting cover. Through theccntieof the box A rises the shuft (l, whichis stepped in 'u. suitable socket in the .plntforni, which supportsth'ejhoit, and which has its bearing in ahole i'nrthe coveiyus oleally, shown in fig. 1 of the drawing, "On this ehuftisinnoxinted. the, sieve D, which is constructed of a, shce t iiietul ifale te,

-perforated ivith a; number of ti'itungnliilbholes a, and providedwit-h teeth b, which may be formed by the pieces punched out in tricking" the holes or which may he produced end secured to thesieve'in uny other siiitable manner. Over the sieve-D is placed thetennulnn head E, w1iich is piovided with atcross-bur, c, from theglower .euriuceofv which extend the pr ojections d. Snid'heudis mounted loosely on the shaft 0; 'and'itlis depressed towards the sieve D by a sfyring ifiwound round the shaft 0: It ishelcl in position in the box A simply by friction ,and the projections 01 are solplaced thattheyflextend between the teeth of the sieve. Under-the; box

A may be secured a'fine sieve, a tta.cho dto the bot'toni'of a" drawer, so thut the clus't 'will'be separated from tho granulated tobacco without tioublc.

-The operation is as follows The tobacco scraps and waste tobacco are filled into the Box' A, the {cover B is fil mly closed, and the shaft C is turned. By the combined actio'n of the projections; diand teeth I; the tobacco is granulated, and mode-to pass through the sieve D; and, a. nail, or a. piece ofiwoodtor hny otherri'gid' matter, gets in between the projections endteeth the spring efyieldg' d the head E 1"is'es o'r't -ns ifouind; "or, if -desired,sa,id head, together with the "sieve,can lie:'remove'd, a.nd injury to the teethflof thosieve,1oi othe parts of the appornt'us is prevented. By these means the tobacco is granulated in an easy and speedy manner, undthe dust is not permitted'to escape in'thc room or building, so that theoperation of granula ting'tobacco can be conducted without injuring the health of or annoying the woi'kmen engaged-in the operation, or: other persons in the same room or building.

Whut I claim as new, and desiret'o secure by LcttersPatent, i s.- I 1. An apparatus for grunuluting tobacco, composed of a; closed box A, movable, toothed sieve D, end yie'hli-nglioud E, with projections-c7, constructed and operating substnntinll'y us und 'for the purpose described. 2. The hrraagemcnt of a, sieve 1D, with teeth-b,constructed and operating substantially as and for the purpose set forth. H i I i 3.- Making th-eSicvc-Qsh'ni't {Lend head'E i-cinovn-hle from the box A, as 01nd for the p'urpose described.
